AUTOMATIC STOVE-LIGHTER.

To all whom t may/concern.' i

Be it known that I, WIIJJAM J. M VANEY, a citizen of the VUnited States,residing at- Lisle,in the county of Dupage and v State of Illinois, jhave inventedl new and useful Improvements in Automatic Stove- Lighters,of which the following is a specification.- y

` This'invention relates to new and useful improvements in automaticlighting devices, and the principal object of the invention is toprovide means for relighting a stove if the same should becomeextinguished through accident. 4 y

Another object of the invention is to provide an electric circuitcombined with athermostat which will automatically complete the circuitand relight the wick, when the same' is extinguished. j Y

Another object of the invention is to pro- Vide a device of thischaracter which is simple and durable in construction, reliable andeiiicient in operation and one which can be manufactured and placed uponthel market at a minimum cost. l

.The invention also consists in certain other V 'features ofconstruction and in the combi-na- Ation and arrangement of the severalparts, to

' rangement of rheostat and-contacts the stove and supported by the rods5 which be hereinafterfully described, lillustrated in the accompanyingdrawings and,I specifically pointed out in the appended claim.

In describing my invention in` detail, reference will be* had tof theaccompanying drawings wherein like characters denote like 1 orcorresponding parts throughout the' sever l'views, and in which:-

said cap being connected to the battery 7.

The thermostat may be composed of the well Aknown form of-waferssuitably-connected together so that when subjected to heat said waferswill expand and bulge outwardly and thus lift the cap from off the plate4. Saidthermostat is supported on the insulated strip 9 so as to be outof electrical contact with the plate. When the thermostat closes thecircuit through'the primary coil of box'7 a current is induced in thesecondary coil,

which is connected with the spark plug so that a'spark is produced atsaid plug. It will thus be lseen that when the stove is lighted the heatthereof will cause the thermostat to ex and so as to raise the cap outthus permitting the cap to come in contact with the plate so as tocomplete the circuit 4of contact wlth the plate and thus break the andcause a spark at'the plug, thereby lightingthe wick again.

iIt is thought from the foregoing description that the advantages andnovel features .y of my invention will be readily apparent.

I desire itto be understood that I may make slight changes 1n theconstruction and I in the combination and arrangementof the severalparta-.provided that such changes scope of the appended claim. What Iclaim is An automatic vlighter for stoves compris-l ing a perforatedplate connected with the top-ofthe stove,` a thermostat on the plateand'insulated therefrom, a4 cap connected with the thermostat" andhaving its edges contacting with the plate in the contracted position ofytheth'ermostat, a spark plug adjacent the wick and electricmeans/controlled by the thermostat for causing; a spark at the
